This book brings together a set of unreleased lectures on contemporary art given by the French philosopher Alain Badiou over a period of just under fifteen years, between 2006 and 2019. The informed reader will recognize that it is not, even closely, the first time Badiou has had an interest in art (an interest that, worth truths, has accompanied him from early on in his career and even in his biography, if we consider that his mother was added to French Literature). However, his reflections on contemporary art, which go through disciplines such as the plastic and visual arts, music, film, poetry or architecture, have not yet been gathered in a single volume a titanic work to come on which the French philosopher is aware.
